COOKING-RANGE.

SPECIFICATION forming part of Letters Patent No. 509,654, dated November28, 1893.

Application filed June 6,1893. Serial Ila-476,708. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES EDWIN DAR- LING, a citizen of the UnitedStates, residing at Auburn, in the county of Androscoggin and State ofMaine, have invented certain new and useful Improvements in Cooking-Ranges; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

The object of my invention is to provide primarily a cooking range whichwill be complete in itself and which will embrace therein the severalfeatures enumerated below: first, a series of two or more horizontallyoscillating and tilting grates each acting independently of the otherand having separate actuating means therefor; secondly, in clinker doorsfor the said range, and, lastly, in other material improvements incooking ranges all of' which will mark a departure from those in vogue,and the details of which will be more fully set forth in theaccompanying specification, in which- Figure 1 represents a plan view ofmy stove. Fig. 2 is a horizontal sectional View of the same. Fig. 3 is afront View. Fig. 4 is a horizontal sectional detail view of the gratesupport. Fig. 5 is a bottom view of the grate and its support detachedfrom the stove. Fig. 6 is a detail vertical sectional view of the same.Fig. 7 is a plan or edge view of one of the clinker doors.

Referring to the drawings A represents the stove or range embodying myimprovements and B the clinker doors. These doors are located preferablyat the front of the range, as shown in this instance, and they areprovided with shanks (t which are secured in a central position to theouter doors and to these are aflixed the inner doors known more properlyas clinker doors which will be more fully hereinafter described. At theupper part of the range front is pivoted the draft door 0. This door ishinged or pivoted horizontally to the range by a rod which is passedthrough eyes 6, which are each integral both with the door and the rangein the usual manner. The door is provided with the usual openings andcut-off slide.

I D, represents the grates which are pivoted in the fire box by means ofsleeves E, secured to the rear wall of the ash box. Supported within thesleeves E are studs F, said studs having one of their ends screwthreaded and held within the sleeves by nuts. The studs F are perforatedat their outer ends as at f and through these perforations pass thepintle or pivot pins f by which the grates are held in position on thestuds. The grates are provided with the usual shank G for engage mentwith the shaker. Upon this shank G are secured cut-offs or deflectors H,which prevent the exit of dust from the fire when the grates are beingactuated. The advantage of this arrangement will be obvious, as theprecipitated ashes which, having, while heated, a tendency to difiusethemselves and arise, will, by this means, he effectually cut oif andretained in the ash box. The opera tion of this portion of my improvedrange will be obvious.

I represents the soot discharge duct which is of the usual form andconnects with the ash pit in the ordinary manner. This duct is providedwith a damper or valve 2', which is designed to regulate the draft fromthe fire box and through the escape pipe.

In the hot air chamber J, are located the several dampers designated bythe letters j, j, 7' The damper j is one of the kind which serves toconcentrate or diffuse the heat in difierent parts of the hot airchamber.

j designates a damper which is located in the stove pipe opening and isoperated by means of the rod j". This damper serves to cut off all draftfrom the fire box A through the air duct or to intensify the chimneydraft and thereby the combustion, by its being 0 thrown open.

The damper 3' is fitted in the top plate of the range, and slides ingrooves cast integral therewith. The free end of this slide passesbeneath the stove pipe collar and serves 9 5 as a cutoff to the pipe. Bythis means a certain predetermined amount of draft may be fixed for therange, and this may be increased or diminished at will.

The clinker doors B, with their shanks a I00 fire box in which clinkersare most liable to gather and from which in this instance they may beeasily reached. The segments serve to complete that part of the fire boxin which they are located and the fuel is thereby kept in place.

The draft door 0, is hinged so as to drop down instead of being swungopen as is ordinarily done and this arrangement saves space and avoidsthe liability of the door being broken off or injuring any one when itis open.

By the arrangement of the grates in the manner herein set forth, it willbe perceived that a part only of the fuel in the fire box may bedisturbed at a time. Less effort will be required to operate each onesingly as in this improvement the shaking and dumping of these gratesmay be more readily and effectually accomplished than by the grates ofordinary construction.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- I 1. A horizontal rotary grate pivotedv toa stud said stud being socketed in asleeve supported on the wall of theash pit substantially as described.

2. In' a stove or range a horizontal sleeve projecting from the rearwall of the ash-pit,

a stud pivoted in said sleeve, a rotary grate pivoted on said studhaving the shank G, and shield H, substantially as described.

3. A rotary grate having a shank or stem thereon, a horizontal studhaving a lug adapted to engage a lug on the sleeve and a shield on thegrate stem conforming to the shape of the firebox and covering theopening therein said sleeve, having the side lug 9 adapted to engage-thelugs on said sleeve and the grate D, having the shanks f and G, andpivoted to the outer end of said stud all substantially as described. V

In testimony whereof I affix my signaturein presence of two witnesses.

CHARLES EDWIN DARLING.
